[Code trace] Android Irda input key mapping

[Irda key mapping to Anroid layer]

Take color key, red, as the example to illustrate the flow to add a new key

==================================================================

- device/hisilicon/godbox/driver/sdk/msp/ecs/drv/ir/ir_s2/hiir_ir2.h

Obtain the keycode of red key and define a MACRO as below:

#define NEC_IR_KEY_RED                                  0xcd

...

Maps Irda keycode to keylabel RED 398:

{NEC_IR_KEY_RED,     KEY_RED},

-------------------------------------------------------------------------------------------

- device/hisilicon/godbox/prebuilt/Vendor_0001_Product_0001.kl

key 398         RED

# key 398 "KEY_RED"

211 is the event value retrieved through onKeyDown() in Android.

- external/webkit/Source/WebKit/android/plugins/ANPKeyCodes.h

kRed_ANPKeyCode = 211,

- frameworks/base/native/include/android/keycodes.h

AKEYCODE_RED = 211,

- frameworks/base/core/java/android/view/KeyEvent.java

public static final int KEYCODE_RED     = 211;

- frameworks/base/core/res/res/values/attrs.xml

<enum name="KEYCODE_RED" value="211" />

-------------------------------------------------------------------------------------------

- frameworks/base/include/ui/KeycodeLabels.h

Maps keylabel RED 398 to 211

{ "RED", 211 },
